I think the biggest issues with some of the "button bloat reductions" are how it can be conflicting design within itself to have abilities that behave substantally different to the ones they're linked with: [High] Jump (animation-locking jump action) -> Mirage Dive (ranged attack, can be executed on any condition.) Wanderer's Minuet (45 second Buff that adds an action and interaction) -> Pitch Perfect. (Added oGCD based on stacks that you press with considerable frequency.) Notice, for instance, how now BRD has 2 songs you press and forget and now for the third one you have to keep it close on your hotbar
I'm not really going to include Kaiten in this because as much as I miss Kaiten already, the changes in damage output to Samurai and the way Midare/Oni Namikiri work are substantial enough for me to accept the removal of it.
Even when logically you can make the argument that you can only execute one after the other, it still feels wrong in a sense of feedback for what you're doing. Imagine if Continuation just built up off of Gnashing Fang and the whole 6 actions, GCD and oGCD follow-ups, were all bound to a single button. That's not remotely as interesting feedback-wise as alternating between the both of them as you'd do now.

I think the direction the FF14 team is taking regarding streamlining jobs is getting dangerous, and they should look into regressing some of these changes as they, in my opinion, reduce some of the fun and skill expression that the game allows for
